Climate change is also change in the availability of water. The greatest risk of global warming relates to water and the pressure on the quantity and quality of water resources, which poses a threat to human lives and ecosystems. An estimated 2.1 billion people lack access to safe water and 4.1 billion people are still deprived of safely managed sanitation. This lack of service coverage and sustainable water resource management has dramatic consequences on health, gender equality, the economy and the environment. The Covid-19 pandemic is a brutal reminder of the need for such basic services.
The water and sanitation sector remains underfinanced and according to the World Bank, more than USD 110 billion would be necessary every year to achieve safe access to water and sanitation targets. And yet, only one-third of current needs are covered.
